3Experimental study on the mechanical properties and consolidation mechanism of microbial grouted backfill显示文摘Backfill mining technology is the practice of returning waste materials underground for both disposal and geotechnical stability,however,a challenge with current technologies is that they commonly require cement-based binders which have a relatively high environmental impact.Finding alternatives to cement-based binders can improve environmental performance and this paper proposes microbial grouted backfill(MGB)as a potential solution.In this paper,the effects of the cementation solution concentration(CSC),volume ratio of bacterial solution to cementation solution(VRBC),particle sizes of the aggregates,and the number of grouting batches on the mechanical properties of MGB are studied.The experimental results show that MGB strength increased,up to a peak value,as CSC was increased,before decreasing as CSC was increased further.The results also show that MGB strength increased,up to a peak value,as VRBC decreased,before decreasing as the VRBC was decreased further.The peak strength was achieved at a CSC of 2 mol/L and a VRBC of 1:9.The strength of the MGB also increased as the number of grouting batches increased.Graded MGB samples showed the highest UCS,25.12 MPa,at particle sizes of 0.2 to 0.8 mm,while full(non-graded)MGB samples displayed mean UCS values ranging from1.56 MPa when the maximum particle size was 0.2 mm,up to 13 MPa when the maximum particle size was 1.2 mm.MGB samples are consolidated by the calcium carbonate that is precipitated during microbial metabolism,and the strength of MGB increases linearly as calcium carbonate content increases.The calcium carbonate minerals produced in MGB materials are primarily calcite,with secondary amounts of vaterite.Xuejie Deng Yu Li Fei Wang Xiaoming Shi Yinchao Yang Xichen Xu Yanli Huang Benjamin de Wit 2022International Journal of Mining Science and Technology2022,32,2:7
4Gravity Changes Before Large Earthquakes in China: 1998-2005显示文摘Although it is well known that coseismic gravity changes take place during an earthquake, previous research has not yielded convincing evidence demonstrating that significant gravity changes occur before large earthquakes. Furthermore, even if we suspect that gravity changes occur before large earthquakes, we have yet to demonstrate how to consistently observe these changes for useful earthquake forecast that would bring benefits to society. We analyzed ground gravity survey data obtained in 1998, 2000, 2002, and 2005 at stations of the Crustal Movement Observation Network of China (CMONOC) and examined gravity changes be-fore the occurrence of nine large (Ms≥6.8) earthquakes that ruptured within or near China's Mainland and Taiwan from November 2001 to August 2008. Results from this analysis show that significant gravity changes occurred across a large region before each of these nine large earthquakes, and these changes were detected by repeated ground gravity surveys through CMONOC. Although these gravity changes were significant, more research is needed to investigate whether these gravity changes could be viewed as precursors of large earthquakes. Limitations and uncertainties in the data include sparseness of the gravity monitoring network, long time intervals between consecutive gravity surveys, inevitable measurement errors, hydrological effects on gravity, and effects of vertical crustal movements on gravity. Based on these observations, we make several recommendations about possible future direc-tions in earthquake-related research using gravity monitoring data.ZHAN F.

5Mesenchymal VEGFA induces aberrant differentiation in heterotopic ossification显示文摘Heterotopic ossification(HO)is a debilitating condition characterized by the pathologic formation of ectopic bone.HO occurs commonly following orthopedic surgeries,burns,and neurologic injuries.While surgical excision may provide palliation,the procedure is often burdened with significant intra-operative blood loss due to a more robust contribution of blood supply to the pathologic bone than to native bone.Based on these clinical observations,we set out to examine the role of vascular signaling in HO.Vascular endothelial growth factor A(VEGFA)has previously been shown to be a crucial pro-angiogenic and pro-osteogenic cue during normal bone development and homeostasis.Our findings,using a validated mouse model of HO,demonstrate that HO lesions are highly vascular,and that VEGFA is critical to ectopic bone formation,despite lacking a contribution of endothelial cells within the developing anlagen.Charles Hwang Simone Marini Amanda KHuber David MStepien Michael Sorkin Shawn Loder Chase APagani John Li Noelle DVisser Kaetlin Vasquez Mohamed AGarada Shuli Li Jiajia Xu Ching-Yun Hsu Paul BYu Aaron WJames Yuji Mishina Shailesh Agarwal Jun Li Benjamin Levi 2019Bone Research2019,7,4:4

7Reduced graphene oxide/silicon nanowire hetero- structures with enhanced photoactivity and superior photoelectrochemical stability显示文摘Silicon nanowires (SiNWs) have been widely studied as light harvesting antennas in photocatalysts due to their ability to absorb broad-spectrum solar radiation, but they are typically limited by poor photoelectrochemical stability. Here, we report the synthesis of reduced graphene oxide-SiNW (rGO-SiNW) heterostructures to achieve greatly improved photocatalytic activity and stability. The SiNWs were synthesized through a metal-assisted electroless etching process and functionalized with reduced graphene oxide (rGO) flakes through a chemical absorption process. Here, the rGO not only functions as a physical protection layer to isolate the SiNWs from the harsh electrochemical environment but also serves as a charge mediator to facilitate the charge separation and transport processes. Furthermore, the rGO may also function as a redox catalyst to ensure efficient utilization of photo-carriers for the desired chemical reactions. Photocatalytic dye degradation studies show that the photoactivity of the heterostructures can be significantly enhanced with an initial activation process and maintained without apparent decay over repeated reaction cycles. Electrochemical and photo- electrochemical studies indicate that the enhanced photoactivity and photostability can be attributed to the more efficient separation of photoexcited charge carriers in SiNWs and the reduced self-oxidation of the surface of the SiNWs during the photocatalytic dye degradation process. The ability to significantly improve the photocatalytic activity and stability in rGO-SiNW heterostructures can not only lead to more opportunities for the application of silicon-based photocatalysts/ photoelectrodes for solar energy harvesting but also provide new insights into the stabilization of other unstable photocatalyticXing Zhong Gongming wang Benjamin Papandrea Mufan Li Yuxi Xu Yu Chen Chih-Yen Chen Hailong Zhou Teng Xue Yongjia Li Dehui Li Yu Huang Xiangfeng Duan 2015Nano Research2015,8,9:4
8Differentiation potential of human adipose tissue derived stem cells into photoreceptors through explants culture and enzyme methods显示文摘● AIM: To investigate the retinal photoreceptor differentiation potential of human orbital adipose tissue-derived stem cells(ADSCs) generated by enzyme(EN) and explant(EX) culture methods.● METHODS: We investigated potentials of human orbital ADSCs to differentiate into photoreceptors through EN and EX culture methods. EN and EX orbital ADSCs were obtained from the same donor during rehabilitative orbital decompression, and then were subject to a 3-step induction using Noggin, DKK-1, IGF-1 and b-FGF at different time points for 38 d. Stem cell, eye-field and photoreceptor-related gene and protein markers were measured by reverse transcription-polymerase chain reaction(RT-PCR) and immunofluorescent(IMF) staining. ● RESULTS: Both EX and EN orbital ADSCs expressed CD133, a marker of cell differentiation. Moreover, PAX6 and rhodopsin, markers of the retinal progenitor cells, were detected from EX and EN orbital ADSCs. In EX orbital ADSCs, PAX6 m RNA was detected on the 17^(th) day and then the rhodopsin m RNA was detected on the 24^(th) day. In contrast, the EN orbital ADSCs expressed PAX6 and rhodopsin m RNA on the 31^(st) day. EX orbital ADSCs expressed rhodopsin protein on the 24^(th) day, while EN orbital ADSCs expressed rhodopsin protein on the 31^(st) day.● CONCLUSION: Orbital ADSCs isolated by direct explants culture show earlier and stronger expressions of markers towards eye field and retinal photoreceptor differentiation than those generated by conventional EN method.Wei-Wei Xu Li Huang Kelvin K.L.Chong Doreen S.Y.Leung Benjamin EL.Li Zheng-Qin Yin Yi-Fei Huang Chi Pui Pang 2017International Journal of Ophthalmology(English edition)2017,10,1:3

10Optical force-induced nonlinearity and self-guiding of light in human red blood cell suspensions显示文摘Osmotic conditions play an important role in the cell properties of human red blood cells(RBCs),which are crucial for the pathological analysis of some blood diseases such as malaria.Over the past decades,numerous efforts have mainly focused on the study of the RBC biomechanical properties that arise from the unique deformability of erythrocytes.Here,we demonstrate nonlinear optical effects from human RBCs suspended in different osmotic solutions.Specifically,we observe self-trapping and scattering-resistant nonlinear propagation of a laser beam through RBC suspensions under all three osmotic conditions,where the strength of the optical nonlinearity increases with osmotic pressure on the cells.This tunable nonlinearity is attributed to optical forces,particularly the forward-scattering and gradient forces.Interestingly,in aged blood samples(with lysed cells),a notably different nonlinear behavior is observed due to the presence of free hemoglobin.We use a theoretical model with an optical force-mediated nonlocal nonlinearity to explain the experimental observations.Our work on light self-guiding through scattering biosoft-matter may introduce new photonic tools for noninvasive biomedical imaging and medical diagnosis.Rekha Gautam Yinxiao Xiang Josh Lamstein Yi Liang Anna Bezryadina Guo Liang Tobias Hansson Benjamin Wetzel Daryl Preece Adam White Matthew Silverman Susan Kazarian Jingjun Xu Roberto Morandotti Zhigang Chen 2019Light(Science & Applications)2019,8,1:3
11Global Wheat Head Detection 2021:An Improved Dataset for Benchmarking Wheat Head Detection Methods显示文摘The Global Wheat Head Detection(GWHD)dataset was created in 2020 and has assembled 193,634 labelled wheat heads from 4700 RGB images acquired from various acquisition platforms and 7 countries/institutions.With an associated competition hosted in Kaggle,GWHD_2020 has successfully attracted attention from both the computer vision and agricultural science communities.From this first experience,a few avenues for improvements have been identified regarding data size,head diversity,and label reliability.To address these issues,the 2020 dataset has been reexamined,relabeled,and complemented by adding 1722 images from 5 additional countries,allowing for 81,553 additional wheat heads.We now release in 2021 a new version of the Global Wheat Head Detection dataset,which is bigger,more diverse,and less noisy than the GWHD_2020 version.Etienne David Mario Serouart Daniel Smith Simon Madec Kaaviya Velumani Shouyang Liu Xu Wang Francisco Pinto Shahameh Shafiee Izzat SATahir Hisashi Tsujimoto Shuhei Nasuda Bangyou Zheng Norbert Kirchgessner Helge Aasen Andreas Hund Pouria Sadhegi-Tehran Koichi Nagasawa Goro Ishikawa Sébastien Dandrifosse Alexis Carlier Benjamin Dumont Benoit Mercatoris Byron Evers Ken Kuroki Haozhou Wang Masanori Ishii Minhajul ABadhon Curtis Pozniak David Shaner LeBauer Morten Lillemo Jesse Poland Scott Chapman Benoit de Solan Frédéric Baret Ian Stavness Wei Guo 2021Plant Phenomics2021,3,1:2

14Role of β-microseminoprotein from prostate cancer initiationto recurrence: A mini-review显示文摘Medline/Pubmed articles relevant to this topic were considered using the search terms ?-microseminoprotein, MSMB, prostate secretory protein of 94 amino acids and PSP94. Full articles were retrieved when the abstract was considered relevant. In addition, other data related to this topic including our own are discussed. Summary of fi ndings-?-microseminoprotein(MSMB) is increasingly being considered as a marker for prostatecancer, as reduced levels have been associated with the disease. Here we review various aspects of this protein including its biological and physiological variants, binding proteins and immune modulation; its importance as a marker for biochemical recurrence of prostate cancer; prostate cancer related splice variants and its therapeutic utility. Two of the most important properties of MSMB are related to anticancer functions and immune modulation. Predominant expression of two(short and full-length) splice variants of MSMB has been observed from normal prostate and several other tissues. In benign prostate hyperplasia the short isoform is dominant, constituting 98% of this isoform, whereas in prostate cancer 96% constitute the fulllength isoform. The MSMB promoter single nucleotide polymorphism rs10993994 with the C allele functions as an activated cyclic adenosine monophosphate response element binding protein binding site. This C variant of rs10993994 could be responsible for the production of splice variants under variable conditions. MSMB has binding motifs to a few known proteins including immunoglobulin G and several Cysteine-rich secretory proteins family proteins. MSMB bound to these proteins is considered as immune modulating. Use of MSMB as a urinary marker for detecting aggressive prostate cancers that could resist radiation and surgical treatments, seems possible, but needs further investigation. The ratio of MSMB splice variants could also be a possible approach in understanding prostate cancers, with higher ratios indicating severe disease.Nishi Karunasinghe Karen Bishop Pamela Murray Yuanye Xu Megan Goudie Lance Ng Shuotun Zhu Dug Yeo Han Lynnette R Ferguson Jonathan Masters Benji Benjamin Michael Holmes 2014World Journal of Clinical Urology2014,3,1:2
15Rapid evolution of regulatory element libraries for tunable transcriptional and translational control of gene expression显示文摘Engineering cell factories for producing biofuels and pharmaceuticals has spurred great interests to develop rapid and efficient synthetic biology tools customized for modular pathway engineering.Along the way,combinatorial gene expression control through modification of regulatory element offered tremendous opportunity for fine-tuning gene expression and generating digital-like genetic circuits.In this report,we present an efficient evolutionary approach to build a range of regulatory control elements.The reported method allows for rapid construction of promoter,5'UTR,terminator and trans-activating RNA libraries.Synthetic overlapping oligos with high portion of degenerate nucleotides flanking the regulatory element could be efficiently assembled to a vector expressing fluorescence reporter.This approach combines high mutation rate of the synthetic DNA with the high assembly efficiency of Gibson Mix.Our constructed library demonstrates broad range of transcriptional or translational gene expression dynamics.Specifically,both the promoter library and 50UTR library exhibits gene expression dynamics spanning across three order of magnitude.The terminator library and trans-activating RNA library displays relatively narrowed gene expression pattern.The reported study provides a versatile toolbox for rapidly constructing a large family of prokaryotic regulatory elements.These libraries also facilitate the implementation of combinatorial pathway engineering principles and the engineering of more efficient microbial cell factory for various biomanufacturing applications.Erqing Jin Lynn Wong Yun Jiao Jake Engel Benjamin Holdridge Peng Xu 2017Synthetic and Systems Biotechnology2017,2,4:2
